Potential relabelling of 'processed material'/'processed material entity'

[sebastianduesing]

At the 2024 COB workshop, it was raised that there is some dissatisfaction with the label of "processed material" (aka "processed material entity" in COB) among the non-OBI-developer community. There was no consensus reached about which label was preferred; some of the proposed labels included "constructed material entity", "artifact", and various permutations involving "manufactured", "designed", etc. Opening this issue as a venue to continue this conversation.
